[Sidefx-houdini-list] Particle Fluid Elasticity

Hi, I started to learn particle fluids. I'm able to control plasticity 
but I'm not able to create a fluid completely elastic like the bunny 
squashed by the foot in the video found at the bottom of this page.


They seem to use an algorithm very similar to Houdini. In Houdini when I 
increase the "Plastic Yield Ratio" I've got to increase to an astronomic 
value the "Plasticity Constant". As soon as I get closer to 0.5 it's no 
longer possible to achieve a stable simulation. I've increased "Max 
Substeps" to 200 and "CFL Condition" to 0.01 still without success.

Actually what I want is to have no plasticity or even better be able to 
control it from no plasticity to full plasticity.

Any ideas?
